Since he's not in any actual light, I can't tell his colors. But from what I can see, he's either going to be Opaque or Pastel. He might be an HM but I'd need a flare pic for that, otherwise he's a super delta

I feel like you're stalking my posts now. ;) Lol, the second picture is the biggest I've ever seen him get, but that's probably because he doesn't have enough room to spread out all the way! He doesn't have any other colors, he seems to barely have any color, even white.

If you get a mirror or something reflective he might flare for you and you can see what he is. A Halfmoon would have a whole 180 spread and would look like the letter D. Delta's are similar but they look more triagular, so they don't get to the full 180. And then Super Delta is almost a HM but the fins are usually rounded at the edges like his are, instead of straight like the letter D.

If you look at my Avatar, well he's not in full flare, but you can see Rembrandt's tail and he's a halfmoon.

Okay yup! Fairly certain he's a regular Delta baby! I find it very interesting how round his tail is though, I know he's not a round tail but maybe somewhere down his line, somebody was!

And it's still hard to see about his color because now he's actually looking like a solid yellow instead of Opaque. If he were Opaque, he would be completely white and there would be no variation to his color. Pastels are generally light pinks, blues, yellows but generally have at least two of those colors if not more. So if he's yellow looking in real life, then I'm going with a Solid Yellow :)

Yeah, any sort of LED or Fluorescent lighting and I'd be able to tell you for certain. Incandescent lighting and any lighting that's not white (like yellow or soft white) is going to be tough to determine his colors because he is a light color.
